When Metropolitan Police Department Assistant Chief Diane Groomes landed in trouble last week, it made more of a splash than the standard internal police personnel matter does. Groomes has been popular among bloggers and neighborhood message board readers, especially in MPD districts where she worked before moving up to oversee the patrol division. The department put her on administrative leave to investigate an allegation she “was involved in compromising” the integrity of a test given to police command staff.

That test, a police source tells City Desk, is called the “intelligence-led policing exam.” It takes between six and eight hours to complete. It’s based on the book Law Enforcement Intelligence by David Carter. The test is partof the department’s professional development training and is about 50 questions long. Police were required to get at least 38 of them correct. The source says word around the department is that Groomes somehow got answers to the test before it was administered, and sent them out to a few commanders via e-mail.

Now the test results will be invalidated, and the entire command staff will have to take a new exam.
